IBS AP14 can control up to 10 drives on a single controller (4 x 8 '' drives + 4 x 5.25 '' drives + 2 x genuine Apple drives). Disk formatting is in IBM format, which makes it easier to exchange disk data with other computers.

IBS AP14 came with patch disk software to use the operating systems DOS 3.3, CP / M 2.2, UCSD Pascal 1.1 and ProDOS of the Apple II computer. In addition, a test disk software for testing components of the interface card is included.

I fixed a bunch of hardware bugs on my personal IBS AP14 card and I want to test it now. For this I need the original patch discs from IBS. Especially from the IBS test disk I promise a lot, because the AP14 card is equipped with a complex SAB1793 floppy disk controller chip and a MC6844 direct memory access controller chip.

I believe that this is the ROM image you are asking for... even that the file name is written incorrectly as "IBS AP-41 ROM.bin" instead of "IBS AP-14 ROM.bin.

This EPROM seems to be bad before reading. Some bytes are good, a lot are bad. I think this is no valid code.
I found a version which is probably in good condition. But I haven't tested it:http://www.ralf-kiefer.de/A2/AP14.BIN
If this is working, please give a response
Regards
Ralf
